I haven't had a chance to read the entire thread, but DH and I have been considering going paleo/primal. I first heard about a paelo lifestyle about 8 years ago while studying anthropology, my teachers mentioned it several times and an old school book (The Paleolithic Prescription by Eaton, Shostak and Konner), which I read and found fascinating, but never tried it. My DH stumbled upon Mark Sissons work about a year ago, and he's been bugging me to get into ever since. I am finishing up my masters in Trad. Chinese medicine, and we have our own nutrition/dietary structure, but it seems to meld well with the paleo/primal thing.
Anyway, I'm looking forward to reading up and jumping in soon! I'm sure I'll have plenty of questions! :)
